This was thought to be the only site known to show the sequence of the early Pleistocene Westleton Beds overlain by "quarttzose gravels" deposited by the proto-Thames river as the Kesgrave Sands & Gravels. The "quartzose gravels" are now thought most likely to be Anglian glacial outwash. The Westleton Beds mainly consist of sand but were quarried here for gravels that were a coastal gravel accumulation, especially gravels washed into large channels, and the site is close to their known inland boundary and throws light on their spatial limits.[4]

Footpaths from Holton go through the site.
